Continuous preparation device of rare earth compound precipitates

Abstract

The invention discloses a continuous preparation device of rare earth compound precipitates. The device comprises a horn-shaped reaction chamber, a self-suction stirring device, a feed pipe I, a feed pipe II, a reflux pipe, a purifying pipe, a clearing chamber, an overflow pipe and a pump I; the self-suction stirring device is fixedly mounted at the top in the horn-shaped reaction chamber; the lower part in the horn-shaped reaction chamber is connected with the feed pipe I and the feed pipe II; the clearing chamber is arranged on one side of the horn-shaped reaction chamber; the lower part of the clearing chamber is conical; the pump I is fixedly mounted at the conical bottom of the clearing chamber; the upper part of the clearing chamber is connected with the overflow pipe; the middle part of the clearing chamber is connected with the purifying pipe; the other end of the purifying pipe is connected to the upper part of the horn-shaped reaction chamber; the lower part of the clearing chamber is connected with the reflux pipe; and the other end of the reflux pipe is connected to the bottom of the horn-shaped reaction chamber. The device can realize continuous preparation of the rare earth compound precipitates, and is excellent in operation continuity, high in productivity, low in energy consumption and high in consistency of produced products.

Description

technical field [0001] The invention belongs to the field of rare earth compound preparation, and in particular relates to a continuous preparation device for rare earth compound precipitation. Background technique [0002] Rare earth metals, also known as rare earth elements, are the general term for the 17 elements of scandium, yttrium, and lanthanide in group IIIB of the periodic table of elements, and are often represented by R or RE. From the discovery of the first rare earth element yttrium in 1794 to the discovery of the natural rare earth element promethium in 1972, it took 178 years for people to find all 17 rare earth elements in nature. The luster of rare earth metals is between silver and iron, and the chemical activity of rare earth metals is very strong. [0003] Rare earth metals have extremely important uses and are an important part of contemporary high-tech new materials. A series of compound semiconductors, electro-optical materials, special alloys, new ...

AI Technical Summary

Problems solved by technology

[0007] For the existing rare earth compound preparation device, the preparation process must be reacted intermittently, that is, the reaction container is completed one after another, and cannot be carried out continuously. The preparation method of this device not only makes the labor productivity low, but also can High consumption, but also lead to poor consistency of the products produced; therefore, with the deepening of processing refinement and automation, all walks of life must carry out corresponding industrial structure adjustments, so it is urgent to improve the above technical problems
